Is AC causing mold on toys and making kids cough?« Back to Previous Page

The fuzzy black spots are likely mold, and your AC is almost certainly contributing to the problem. In Dubai's humid climate, AC systems that aren't properly maintained create massive condensation. This moisture, combined with the lack of light and air circulation in a storage cupboard under a window, creates the perfect breeding ground for mold. The coughing is a common reaction to mold spores circulating in the air.

For the toys, first assess if they are salvageable. Non-porous plastic toys can be cleaned with a solution of one part white vinegar to four parts water. Scrub thoroughly, rinse, and dry completely in the sun. Porous toys like stuffed animals are much harder to decontaminate and are often best discarded for health reasons.

The critical step is addressing the source. The mold on the toys is a symptom of a moisture issue in that room. The storage cupboard is likely a cold spot where humidity is condensing. You must improve ventilation in that area and have your AC system inspected. A clogged drain line or dirty cooling coils are frequent culprits that cause excess humidity and mold growth inside AC units, which then spreads spores throughout your home.

For a situation involving children's health and visible growth, a professional inspection is strongly recommended to identify all contamination sources. They can perform an air quality test to pinpoint the spore types and concentration, which dictates the necessary remediation steps to make your apartment safe.
